N Dimensional Finite Wavelet Filters
Si-Long Peng · Journal of Computational Mathematics · 2003
In this paper, a large class of $n$ dimensional orthogonal and biorthogonal wavelet filters (lowpass and highpass) are presented in explicit expression. We also characterize orthogonal filters with linear phase in this case. Some examples are also given, including nonseparable orthogonal and biorthogonal filters with linear phase.
